android布局弹起,Android 输入框弹起时顶起布局(与ScrollView一起使用)

scrollView1为布局文件中ScrollView的id

// 监听键盘弹起或关闭(ScrollView)

scrollView1.addOnLayoutChangeListener(new View.OnLayoutChangeListener() {

@Override

public void onLayoutChange(final View v, int left, int top, int right, int bottom, int oldLeft, int oldTop, int oldRight, int oldBottom) {

if (oldBottom != 0 && bottom != 0 && (oldBottom - bottom > 100)) {

// Toast.makeText(getApplicationContext(), "监听到软键盘弹起...", Toast.LENGTH_SHORT).show();

// scrollView.fullScroll(ScrollView.FOCUS_DOWN);(会导致输入框失去焦点)

// 获得屏幕

View decorView = getWindow().getDecorView();

ViewUtil.scrollToBottom(decorView, v);

} else if (oldBottom != 0 && bottom != 0 && (bottom - oldBottom > 100)) {

// Toast.makeText(getApplicationContext(), "监听到软件盘关闭...", Toast.LENGTH_SHORT).show();

}

}

});
