<TextView
android:id="@+id/businesscardsingle_content_abstract"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="5dp"
android:lineSpacingMultiplier="1.0"
android:lines="6"
android:text="@string/agrinbusiness_content"

在JAVA代码中控制文本的显示行数
ViewTreeObserver observer = textAbstract.getViewTreeObserver(); //textAbstract为TextView控件
observer.addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {
ViewTreeObserver obs = textAbstract.getViewTreeObserver();
obs.removeGlobalOnLayoutListener(this);
if(textAbstract.getLineCount() > 6) //判断行数大于多少时改变
{
int lineEndIndex = textAbstract.getLayout().getLineEnd(5); //设置第六行打省略号
String text = textAbstract.getText().subSequence(0, lineEndIndex-3) +"...";
textAbstract.setText(text);
}
}
});
