View 的 getLeft() 和 getRight() 和 getTop() 和 getBottom()分别对应的是哪些坐标：
top 是左上角纵坐标，left 是左上角横坐标，right 是右下角横坐标，bottom 是右下角纵坐标
创建了一个测试项目来获取View位置，在onCreate中获取到的位置为0。
xml的内容
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.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"
android:background="#ffffff"
tools:context="com.pistol.viewtest.MainActivity">
<TextView
android:id="@+id/tv_position"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="5dp"
android:text="Hello World!"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent"/>
</android.support.constraint.ConstraintLayout>
Activity代码如下：
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
tvPosition = (TextView) findViewById(R.id.tv_position);
Log.e("onCreate", "````````````````````````````````````````");
Log.e("Left", "=" + tvPosition.getLeft());
Log.e("Top", "=" + tvPosition.getTop());
Log.e("Right", "=" + tvPosition.getRight());
Log.e("Bottom", "=" + tvPosition.getBottom());
}
结果：
03-22 15:10:47.440 18055-18055/com.pistol.viewtest E/onCreate: ````````````````````````````````````````
03-22 15:10:47.440 18055-18055/com.pistol.viewtest E/Left: =0
03-22 15:10:47.440 18055-18055/com.pistol.viewtest E/Top: =0
03-22 15:10:47.441 18055-18055/com.pistol.viewtest E/Right: =0
03-22 15:10:47.441 18055-18055/com.pistol.viewtest E/Bottom: =0
如何可以在oncreate中获取呢
方法一：
private void measureOne() {
ViewTreeObserver vto = tvPosition.getViewTreeObserver();
vto.addOnPreDrawListener(new ViewTreeObserver.OnPreDrawListener() {
@Override
public boolean onPreDraw() {
//防止二次调用
tvPosition.getViewTreeObserver().removeOnPreDrawListener(this);
Log.e("onPreDraw", "````````````````````````````````````````");
Log.e("Left", "=" + tvPosition.getLeft());
Log.e("Top", "=" + tvPosition.getTop());
Log.e("Right", "=" + tvPosition.getRight());
Log.e("Bottom", "=" + tvPosition.getBottom());
return true;
}
});
}
我用的方法一
结果：
03-22 15:10:47.502 18055-18055/com.pistol.viewtest E/onPreDraw: ````````````````````````````````````````
03-22 15:10:47.502 18055-18055/com.pistol.viewtest E/Left: =413
03-22 15:10:47.506 18055-18055/com.pistol.viewtest E/Top: =803
03-22 15:10:47.506 18055-18055/com.pistol.viewtest E/Right: =668
03-22 15:10:47.506 18055-18055/com.pistol.viewtest E/Bottom: =890
方法二：
private void measureTwo() {
ViewTreeObserver vto = tvPosition.getViewTreeObserver();
vto.addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {
//防止二次调用
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
tvPosition.getViewTreeObserver().removeOnGlobalLayoutListener(this);
} else {
tvPosition.getViewTreeObserver().removeGlobalOnLayoutListener(this);
}
Log.e("onGlobalLayout", "````````````````````````````````````````");
Log.e("Left", "=" + tvPosition.getLeft());
Log.e("Top", "=" + tvPosition.getTop());
Log.e("Right", "=" + tvPosition.getRight());
Log.e("Bottom", "=" + tvPosition.getBottom());
}
});
}
结果：
03-22 15:10:47.501 18055-18055/com.pistol.viewtest E/onGlobalLayout: ````````````````````````````````````````
03-22 15:10:47.502 18055-18055/com.pistol.viewtest E/Left: =413
