Android实现多条Toast快速显示（强制中止上一条Toast的显示）

Android实现多条Toast快速显示

Toast.makeText(this, "弹出Toast", Toast.LENGTH_SHORT).show();

实现Toast显示的时候，中止上一条Toast的显示

private Toast toast = null;
/**
* 弹出Toast(中断正在显示的Toast)
*/
public void showToast(View view) {
if (toast == null) {
toast = Toast.makeText(getApplicationContext(), "", Toast.LENGTH_SHORT);
}
toast.setText("弹出Toast(中断正在显示的Toast)");
toast.show();
}

工具类（为了方便，可以直接复制粘贴使用）

package googleanalytics.example.com.kqwtoastdemo;

import android.content.Context;
import android.widget.Toast;

/**
* Created by kongqw on 2015/9/28.
*/
public class ToastUtile {

// 构造方法私有化 不允许new对象
private ToastUtile() {
}

// Toast对象
private static Toast toast = null;

/**
* 显示Toast
*/
public static void showText(Context context, String text) {
if (toast == null) {
toast = Toast.makeText(context, "", Toast.LENGTH_SHORT);
}
toast.setText(text);
toast.show();
}
}

测试类

package googleanalytics.example.com.kqwtoastdemo;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Toast;

public class MainActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}

/**
* 弹出Toast
*/
public void showToastDefault(View view) {
Toast.makeText(this, "弹出Toast", Toast.LENGTH_SHORT).show();
}

private int mShowCount = 0;

/**
* 弹出Toast(中断正在显示的Toast)
*/
public void showToast(View view) {
ToastUtile.showText(this, "弹出Toast(中断正在显示的Toast) " + mShowCount++);
}
}
