就和类似qq消息双击就就会变大一样的，我想问下怎么写双击监听textview事件，网上试了什么onclick判断时间小于多少的方法不行，重写ontouch也不行，而且我看GestureDetector 的构造方法也只有监听整个content，只能对上下文进行双击监听。
简单描述：就是对textview进行双击监听，最好有代码，谢谢......
这个我实现了，但是也是用记录上次点击时间的方法，代码给你看下。
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.TextView;
import com.sinovoice.test.R;
public class DoubleClickActivity extends Activity {
private static final String TAG = "DoubleClickActivity";
private int clickCount;
private long preClickTime;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
TextView tv = (TextView) findViewById(R.id.tv_main);
clickCount = 0;
tv.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
if (clickCount == 0) {
preClickTime = System.currentTimeMillis();
clickCount++;
} else if (clickCount == 1) {
long curTime = System.currentTimeMillis();
if((curTime - preClickTime) < 500){
doubleClick();
}
clickCount = 0;
preClickTime = 0;
}else{
Log.e(TAG, "clickCount = " + clickCount);
clickCount = 0;
preClickTime = 0;
}
}
});
}
private void doubleClick() {
Log.i(TAG, "double click");
}
}
public abstract class OnDoubleClickLinstener implements OnclickListener{
public abstract void onDoubleClick(View v);
@override
public void onClick(View v){
if(ToolUtils.isNotDoubleClick()){
return ;
}
onDoubleClick(v);
}
}
判断类
public class ToolUtils{
private static long lastClickTime = 0;
public static boolean isNotDoubleClick(){
long time = System.currentTimeMillis();
long diff = time - lastClickTime;
lastClickTime = time;
if( diff>0 && diff<500 ){
return false;
}
return ture;
}
}
