使用Toast：
package com.huatec.myapplication;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.Gravity;
import android.view.View;
import android.widget.Button;
public class MainActivity extends AppCompatActivity {
private Button hintToast1;
private Button hintToast2;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
hintToast1 = findViewById(R.id.hint_toast);
hintToast2 = findViewById(R.id.hint_toast2);
//按钮1
hintToast1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
new MyToast.Builder(MainActivity.this)
.setMessage("你好吗？")//设置提示文字
.setBackgroundColor(0x88ff4587)//设置背景颜色
.setGravity(Gravity.CENTER)//设置吐司位置
.build()//创建吐司
.show();
}
});
//按钮2
hintToast2.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
new MyToast.Builder(MainActivity.this)
.setMessage("你好吗？")
.setBackgroundColor(0x88ff4587)
.setGravity(Gravity.CENTER)
.setIcon(R.mipmap.ic_launcher)//设置图标
.showIcon(true)//是否显示图标
.build()
.show();
}
});
}
}
