假设有一个Layout,布局如下:
splash.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:gravity="center_vertical|center_horizontal"
android:orientation="horizontal" android:layout_width="fill_parent"
android:layout_height="fill_parent" android:id="@+id/progressShadow">
<ProgressBar android:layout_gravity="center_vertical"
android:id="@+id/progress" android:layout_width="50dp"
android:layout_height="50dp">
</ProgressBar>
<TextView android:id="@+id/current_action"
android:layout_toRightOf="@id/progress" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:layout_marginLeft="5.0dip"
android:text="@string/loading" android:textSize="20sp">
</TextView>
</LinearLayout>
我们可以通过如下方式来动态添加到一个Activity页面上面:
private int KEY_PROGRESS_LAYOUT_ID = 1;
private Handler handler = new Handler();
public void add() {
LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(
320, LinearLayout.LayoutParams.FILL_PARENT);
LayoutInflater inflater = (LayoutInflater) login
.getSystemService(Login.LAYOUT_INFLATER_SERVICE);
layout = inflater.inflate(R.layout.splash, null);
layout.setId(KEY_PROGRESS_LAYOUT_ID);
// progressShadow = (LinearLayout) layout
// .findViewById(Constants.KEY_PROGRESS_LAYOUT_ID);
final TextView tv = (TextView) layout.findViewById(R.id.current_action);
handler.post(new Runnable() {
public void run() {
tv.setText("Loading....");
}
});
Drawable ico = login.getResources().getDrawable(R.drawable.dbg);
layout.setBackgroundDrawable(ico);
ico.mutate().setAlpha(200);
animLayout.addView(view, layoutParams);
}
