Android - 文本图像右侧水平重叠屏幕

Android - Image Right of Text Overlaps Screen Horizontally

我正在尝试在 TextView 的右侧添加一个单行图像。 当文本很短时,它工作正常。问题是当文本太大并且被截断时。文字填满LinearLayout,图片不在屏幕上

短文本:

长文本:

代码:

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <LinearLayout
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintTop_toTopOf="parent">

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textSize="32sp"
            android:ellipsize="end"
            android:maxLines="1"
            tools:text="Lorem ipsum dolor sit amet, consectetur"/>

        <androidx.appcompat.widget.AppCompatImageView
            android:id="@+id/ivInfectedDevOtherInfoIcon"
            android:layout_width="40dp"
            android:layout_height="40dp"
            android:layout_marginStart="8dp"
            app:layout_constraintTop_toTopOf="@+id/ivInfectedDevOtherName"
            app:layout_constraintStart_toEndOf="@+id/ivInfectedDevOtherName"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintHorizontal_bias="0"
            app:srcCompat="@drawable/ic_tv" />

    </LinearLayout>
</androidx.constraintlayout.widget.ConstraintLayout>

当文本很长时,如何使图像停靠在右侧以使其不重叠?

编辑 1: 来自评论:

This works when the text is long and is truncated. When the text is short the image stays docked at the right and there is a bigger gap then the intended 8dp between the two element

因此,除非将视图直接插入 TextView 中,否则您正在寻找的行为将不起作用,它将测量当前宽度并在到达 drawable 末尾时截断& 不是文字。所以你可以创建这样的组件或使用 drawableEnddrawableEndCompat.

使用 drawableEndCompat 你的布局看起来像这样(你可以删除 LinearLayout IMO):

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <LinearLayout
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent">

        <TextView
            android:id="@+id/tvText"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:ellipsize="end"
            android:maxLines="1"
            android:textSize="32sp"
            app:drawableEndCompat="@drawable/ic_add"
            android:text="Lorem cd" />

    </LinearLayout>
</androidx.constraintlayout.widget.ConstraintLayout>

如果您想点击 drawableEndCompat,那么您可以这样查看 SO 上的答案:Implement onClick only for a TextView compound drawable

示例:

@SuppressLint("ClickableViewAccessibility")
    private void setOnEndClickListener() {
        TextView txtview = (TextView) findViewById(R.id.tvText);
        txtview.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                if (event.getAction() == MotionEvent.ACTION_UP) {
                    if (event.getRawX() >= txtview.getRight() - txtview.getTotalPaddingRight()) {
                        Log.d("MG-onClick", "Drawable Clicked");
                        return true;
                    }
                }
                return true;
            }
        });
    }

旧答案:

layout_weight=1layout_width="0dp" 添加到您的 TextView

所以它看起来像这样:

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <LinearLayout
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintTop_toTopOf="parent">

        <TextView
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:textSize="32sp"
            android:ellipsize="end"
            android:maxLines="1"
            android:layout_weight="1"
            tools:text="Lorem ipsum dolor sit amet, consectetur"/>

        <androidx.appcompat.widget.AppCompatImageView
            android:id="@+id/ivInfectedDevOtherInfoIcon"
            android:layout_width="40dp"
            android:layout_height="40dp"
            android:layout_marginStart="8dp"
            app:layout_constraintTop_toTopOf="@+id/ivInfectedDevOtherName"
            app:layout_constraintStart_toEndOf="@+id/ivInfectedDevOtherName"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintHorizontal_bias="0"
            app:srcCompat="@drawable/ic_add" />

    </LinearLayout>
</androidx.constraintlayout.widget.ConstraintLayout>

试试这个方法...

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout 
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent">

<LinearLayout
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintTop_toTopOf="parent">

    <TextView
        android:layout_width="wrap_content"
        android:layout_weight="8"
        android:layout_height="wrap_content"
        android:textSize="32sp"
        android:ellipsize="end"
        android:maxLines="1"
        tools:text="Lorem ipsum dolor sit amet, consectetur"/>

    <androidx.appcompat.widget.AppCompatImageView
        android:id="@+id/ivInfectedDevOtherInfoIcon"
        android:layout_width="0dp"
        android:layout_weight="2"
        android:layout_height="40dp"
        android:layout_marginStart="8dp"
        app:layout_constraintTop_toTopOf="@+id/ivInfectedDevOtherName"
        app:layout_constraintStart_toEndOf="@+id/ivInfectedDevOtherName"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintHorizontal_bias="0"
        app:srcCompat="@drawable/ic_tv" />

  </LinearLayout>
  </androidx.constraintlayout.widget.ConstraintLayout>

只需对您的 xml 布局进行以下更改:

1.In 线性布局 添加:

android:layout_width="wrap_content"
app:layout_constraintHorizontal_bias="0"

2.In TextView 添加:

android:layout_weight="1"

3.In AppCompatImageView 添加:

android:layout_weight="0"

最终 xml 布局如下所示:

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintHorizontal_bias="0">

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textSize="32sp"
            android:ellipsize="end"
            android:layout_weight="1"
            android:maxLines="1"
            tools:text="Lorem ipsum dolor sit amet, consectetur "/>

        <androidx.appcompat.widget.AppCompatImageView
            android:id="@+id/ivInfectedDevOtherInfoIcon"
            android:layout_width="40dp"
            android:layout_height="40dp"
            android:layout_marginStart="8dp"
            android:layout_weight="0"
            app:layout_constraintTop_toTopOf="@+id/ivInfectedDevOtherName"
            app:layout_constraintStart_toEndOf="@+id/ivInfectedDevOtherName"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintHorizontal_bias="0"
            app:srcCompat="@drawable/ic_tv" />

    </LinearLayout>
</androidx.constraintlayout.widget.ConstraintLayout>
