TextView最后一行实现省略号

main.xml如下:

<RelativeLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

    <TextView
        android:id="@+id/textView"
        android:layout_width="70dip"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:maxLines="5"
    />

</RelativeLayout>

MainActivity如下:

import android.os.Bundle;
import android.view.ViewTreeObserver;
import android.view.ViewTreeObserver.OnGlobalLayoutListener;
import android.widget.TextView;
import android.app.Activity;
public class MainActivity extends Activity {
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
		init();
	}

	private void init() {
		final TextView mTextView = (TextView) findViewById(R.id.textView);
		mTextView.setText("测试文本控件的属性" + "测试文本控件的属性" + "测试文本控件的属性" 
		                 + "测试文本控件的属性"+ "测试文本控件的属性" + "测试文本控件的属性");
		ViewTreeObserver viewTreeObserver = mTextView.getViewTreeObserver();
		viewTreeObserver.addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
					@Override
					public void onGlobalLayout() {
						ViewTreeObserver obs = mTextView.getViewTreeObserver();
						obs.removeGlobalOnLayoutListener(this);
						int lineCount = mTextView.getLineCount();
						int lineVisibleEnd = mTextView.getLayout().getLineVisibleEnd(5);
						String text = mTextView.getText().subSequence(0,lineVisibleEnd - 6)+ "...";
						mTextView.setText(text);
					}
				});
	}
}
