使用Bundle传递复杂数据

第一种方法

1、在第一个activity中

<span style="font-size:18px;"><span style="white-space:pre">	</span>Button start = (Button)findViewById(R.id.toSecond);
start.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent i = new Intent(MainActivity.this,SecondActivity.class);
Bundle data = new Bundle();
data.putString("name","Jack");
data.putInt("age",23);
i.putExtras(data);
startActivity(i);
}
});</span>

2、在第二个activity中进行数据读取

<span style="font-size:18px;"><span style="font-size:18px;">Intent i = getIntent();
Bundle data = i.getExtras();
TextView textView = (TextView) findViewById(R.id.textView);
textView.setText(String.format("name=%s,age=%d,name1=%s",data.getString("name"),data.getInt("age"),data.getString("name1","LJaer")));</span></span>

通过向intent中传入一个Bundle类型的字符串进行数据传递，name1 没有数值，进行默认LJaer设置

第二种方法

1、在第一个activity中

<span style="font-size:18px;">start.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent i = new Intent(MainActivity.this,SecondActivity.class);
Bundle data = new Bundle();
data.putString("name","Jack");
data.putInt("age",23);
//i.putExtras(data);
i.putExtra("info",data);
startActivity(i);
}
});</span>

<span style="font-size:18px;">
</span>

<span style="font-size:18px;">2、在第二个activity中</span>

<pre name="code" class="java"><span style="font-size:18px;">Intent i = getIntent();
//Bundle data = i.getExtras();
Bundle data = i.getBundleExtra("info");
TextView textView = (TextView) findViewById(R.id.textView);
textView.setText(String.format("name=%s,age=%d,name1=%s",data.getString("name"),data.getInt("age"),data.getString("name1","LJaer")));</span>
