我有一個開關按鈕,我想從中傳遞不同的值(1或2)到下一個活動進行計算。但我總是得到0.任何幫助?Android的意圖不會傳遞開關的值
Switch mySwitch = (Switch) findViewById(R.id.edit_home);
// set the switch to ON
mySwitch.setChecked(true);
// attach a listener to check for changes in state
mySwitch.setOnCheckedChangeListener(new Switch.OnCheckedChangeListener() {
public void onCheckedChanged(CompoundButton buttonView,
boolean isChecked) {
if (isChecked) {
double input5 = 2;
Intent intentx=new Intent(MainActivity.this,Main2Activity.class);
intentx.putExtra("IFValue",input5);
startActivity(intentx);
Toast.makeText(getApplicationContext(), "Home field is important advantage",
Toast.LENGTH_SHORT).show();
} else {
double input5 = 1;
Intent intenty=new Intent(MainActivity.this,Main2Activity.class);
intenty.putExtra("IFValue",input5);
startActivity(intentx);
Toast.makeText(getApplicationContext(),
"Home field is not advantage", Toast.LENGTH_SHORT).show();
}
}
});
在接下來的活動:
Bundle bundle = getIntent().getExtras();
double input5 = bundle.getDouble("IFValue");
編輯:我想發送值(輸入5)到下一個活動,但如果我加入startActivity(intentx)開關的內部;然後立即去那裏,而不是當我按下按鈕(buttonForward),因爲我想。
休息代碼:
Switch mySwitch = (Switch) findViewById(R.id.edit_home);
// set the switch to ON
mySwitch.setChecked(true);
// attach a listener to check for changes in state
mySwitch.setOnCheckedChangeListener(new Switch.OnCheckedChangeListener() {
public void onCheckedChanged(CompoundButton buttonView,
boolean isChecked) {
if (isChecked == true) {
double input5 = 2;
Intent intentx=new Intent(MainActivity.this,Main2Activity.class);
intentx.putExtra("IFValue",input5);
startActivity(intentx);
Toast.makeText(getApplicationContext(), "Home field is important advantage",
Toast.LENGTH_SHORT).show();
} else {
double input5 = 1;
Intent intenty=new Intent(MainActivity.this,Main2Activity.class);
intenty.putExtra("IFValue",input5);
startActivity(intenty);
Toast.makeText(getApplicationContext(),
"Home field is not advantage", Toast.LENGTH_SHORT).show();
}
}
});
Button buttonForward = (Button) findViewById(R.id.buttonToMain2);
buttonForward.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View arg0) {
EditText edit_team = (EditText) findViewById(R.id.edit_team);
EditText edit_form = (EditText) findViewById(R.id.edit_form);
EditText edit_import = (EditText) findViewById(R.id.edit_import);
String ekipa1 = edit_team.getText().toString();
final double input2 = Double.valueOf(qualityControl.getProgress());
final double input3 = Double.valueOf(edit_form.getText().toString());
final double input4 = Double.valueOf(ratingBar.getRating());
final double input6 = Double.valueOf(edit_import.getText().toString());
Intent intent=new Intent(MainActivity.this,Main2Activity.class);
intent.putExtra("Value",input2);
intent.putExtra("Value1",input3);
intent.putExtra("Value2",input4);
intent.putExtra("Value4",input6);
intent.putExtra("team1", ekipa1);
startActivity(intent);
}
});
檢查你的價值器isChecked我認爲這不會改變從PLS breakeposints –
哪裏是startActivty(意向)首先檢查它;功能?你如何開始下一個活動? – Hulk
@BhanuSharma我怎麼能解決它? – user3041073
