android 防连点

一般在做提交订单或者发起联网请求的操作时候，需要处理连续点击的问题，这个有很多处理方案，

比如，设置标记 tag，发起请求之后就设置按钮不可点击等等，下面的只是其中一种，代码如下：

import android.util.Log;
import android.view.View;
import java.util.Calendar;

/**

 */

public abstract class NoDoubleListener implements View.OnClickListener {
    public static final int MIN_CLICK_DELAY_TIME = 3000;
    private static final String TAG ="NoDoubleListener" ;
    private long lastClickTime = 0;

    @Override
    public void onClick(View v) {
        long currentTime = Calendar.getInstance().getTimeInMillis();
        if (currentTime - lastClickTime > MIN_CLICK_DELAY_TIME) {
            lastClickTime = currentTime;
            onNoDoubleClick(v);
        }else {
            Log.w(TAG,"点击过快");
        }
    }
    protected abstract void onNoDoubleClick(View v);
}

使用方式：

public class DemoActivity extends AppCompatActivity {
    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_test);
        TextView tv  = (TextView) findViewById(R.id.tv_btn);
        tv.setOnClickListener(new NoDoubleListener() {
            @Override
            protected void onNoDoubleClick(View v) {
                Toast.makeText(DemoActivity.this,"点击了按钮", Toast.LENGTH_SHORT).show();
            }
        });
    }
}

最近在学习kotlin 调用方式一起贴上来

class TestActivity : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_test)
        val tv  = findViewById(R.id.test_tv) as TextView
        tv.setOnClickListener(object : NoDoubleListener() {
            override fun onNoDoubleClick(v: View) {
                Toast.makeText(this@TestActivity,"点击了按钮",Toast.LENGTH_SHORT).show()
            }
        })
    }
}
